Company Profile
Enterprises listed in the Key Promotion Catalogue of Practical Water Conservancy Technologies by the Science and Technology Promotion Center of the Ministry of Water Resources.
Sanhuali was founded in 2008, with its production base located in the Qingdao High-tech Zone of Shandong Province. As a provincial-level specialized, refined, distinctive, and innovative enterprise, it is committed to addressing the longstanding challenge of pipeline freeze‑protection—issues that conventional insulation methods cannot resolve—through independently developed energy‑saving, freeze‑proof technology for water supply pipelines. The company also provides comprehensive solutions for municipal water‑supply network construction. In 2016, it was listed on the Qilu Equity Exchange Center.
Sanhuali takes innovation as its core, striving to become a pioneer in China’s water‑conservation pipeline energy‑saving and freeze‑protection sector. By leveraging technological innovation, business‑model innovation, and innovations in management and institutional mechanisms as its three key drivers, the company aims to grow into one of the country’s leading specialized enterprises in freeze‑protection technology, while building a globally recognized premium brand for energy‑efficient, freeze‑proof equipment for water‑supply pipelines.
The company has established a domestic production and R&D base in the Qingdao High-Tech Industrial Development Zone, Shandong Province. Its core technologies include the SHL pipeline freeze‑proof valve, the SCS freeze‑proof plug, the 3FT multi‑functional fire hydrant, the HWZ infrared smart freeze‑proof device, as well as the SND high‑pressure water‑saving freeze‑proof flushing plug and the ZNF building‑specific smart freeze‑proof device—among many other series of aerodynamic vacuum‑based freeze‑prevention products. Annually, the company can produce 200,000 sets of 3FT multi‑functional fire hydrants, 5 million sets of SCS freeze‑proof plugs, and over 2 million NFV freeze‑proof valves. Its products have been incorporated into the “12‑Series Architectural Standard Design Atlas” for six provinces in North China, and the company now offers comprehensive solutions covering municipal water networks, rural drinking‑water safety initiatives reaching every village, smart fire‑protection systems, integrated solar‑energy applications, rural dry‑toilet upgrades, agricultural water‑saving irrigation, and energy‑efficient green building projects. These efforts contribute to targeted poverty alleviation, improved public welfare, and enhanced public safety.
Sanhuali is currently involved in infrastructure development projects across multiple regions in China, with plans to establish 100 demonstration projects nationwide, while also actively participating in the Belt and Road Initiative and expanding its presence in international markets.
As a leading domestic manufacturer and solution provider of freeze‑proof equipment for municipal water supply systems, Sanhuali has established dozens of partner enterprises and projects nationwide. Its innovative demonstration projects across various regions have been recognized by relevant authorities. In 2017, the company was successively included in the Ministry of Water Resources’ “Key Promotion Catalogue of Advanced and Practical Water‑Conservation Technologies” and the “National Catalogue of Water‑Saving Products.” Furthermore, Sanhuali has forged industry‑university‑research collaboration partnerships with numerous related institutions, making significant contributions to the orderly and rapid advancement of energy‑efficient, freeze‑proof technologies for water‑supply pipelines in China.
For many years, the promotion and application of Sanhuali’s technological products have consistently attracted strong interest from the capital markets, earning the company recognition as a trusted investment target among numerous prominent investment institutions. Backed by robust technological capabilities, formidable financing capacity, and solid financial strength, the company plans to list on the STAR Market through widespread market adoption.
Sanhuali allocates a fixed percentage of its annual net profit to research and development, maintaining a team of R&D professionals and expert consultants. The company holds dozens of software copyrights and has achieved numerous scientific and technological breakthroughs. It has undertaken multiple innovation projects at various levels and established the Weifang Municipal Engineering Technology Research Center for Anti‑Freeze Equipment in Water Supply Pipelines. Furthermore, it plans to set up engineering technology centers for energy‑saving water‑conservation equipment in Northeast China, Northwest China, North China, and Central China. Sanhuali also engages in collaborative exchanges with numerous domestic universities and intends to participate in the establishment of a National Strategic Alliance for Technological Innovation in the Energy‑Saving and Anti‑Freeze Industry for Water Supply Pipelines, thereby fostering coordinated development across the entire water‑conservation value chain.
Looking ahead, Sanhuali will remain committed to its corporate mission of “fulfilling social responsibility and building an ecological civilization.” By continuously advancing technological innovation and refining its industrial chain, the company will make meaningful contributions to ensuring water security in both urban and rural areas, supporting municipal infrastructure development, and driving industrial upgrading, thereby showcasing the remarkable innovative strength of Chinese enterprises on the global stage.
